Eight Burst Nebula

NGC 3132 is also known as the Southern Ring Nebula or, more commonly, as the Eight-Burst Nebula because of its figure-8 appearance through small telescopes. It is a very bright, asymmetric planetary nebula of approximately 0.4 light years across and is about 2,000 light-years away in the southern constellation Vela. It is receding from us at 49 kilometers per second.

This expanding cloud of gas is one of the nearest known planetary nebulae. The gases expand away from the central star at a speed of about 14.4 kilometers per second. Interestingly, neither the unusual shape of the surrounding cooler shell nor the structure and placements of the cool filamentary dust lanes running across NGC 3132 are well understood.

The colour mapping is chosen to mimic RGB:

Ha+25% Sii -->Red

OIII-->Green

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
